In the thirteen years since then, I've learned a lot! One thing I've learned is, no matter how much I may want my children to respond with first time obedience, they are not little robots. They have their own wills, which they exercise often.
Another thing I've learned is the importance of extending grace to my children. It's taken me a long time to understand this. God gave me grace when He sent His Son to die on the cross for my sins. I don't deserve it. I'll never deserve it, but He granted it anyway. In the same way, I need to grant my children grace, especially when their "disobedience" is simply a result of being children.
This isn't to say that I don't discipline my children; I do. I still expect them to do the right thing, but I also understand that there are going to be times they'll mess up. I can't expect them to be perfect, especially when I fail on a daily basis. Sometimes, the most important thing I can do to teach them about God's love is to extend a little grace myself.
